Installing a RADWIN MHS Appendix K
WinLink™ 1000 User Manual Release 1.9 K-4
Figure K-3: How to connect the IDUs to the Patch Panel
In what follows, it will be assumed that –
1. We will depart from our usual Site A / Site B conventions. Sites A and B
on the primary link will be Sites 1.2 and 1.4 respectively. The corre-
sponding sites on the secondary link will be Sites 2.2 and 2.4. The site
names reflect their IP addresses. This is a useful convention and is
reflected in the screen captures below..
2. The link will be managed from Site 1.2; Site 1.4 may be a remote site.
3. The links intended as the primary and secondary will be referred to their
respective names, Primary Link and Secondary Link as shown in
Figure K-1 above, despite their having yet to be installed.
¾ To install a Hot Standby Link:
1. Set up Primary Link in the usual way. Ensure that it is fully operational in
accordance with the relevant instructions in Part 1 of the User Manual.
2. Connect user equipment to Site 1.4.
3. At Site 1.2, disconnect the TDM cables from the external equipment or
disconnect external equipment from the Hot Standby Patch Panel.
4. The HSS cable (connecting the ODUs) should be connected at Site 1.2.
The ODU belonging to the primary link should be configured as HSM,
whereas the ODU belonging to the secondary link should be configured
as HSC-CT.
Note
•With RADWIN 2000 links you can protect up to 16 TDM ports. To pro-
tect more than eight TDM ports use two Patch Panels at each site.
• Ethernet services are carried independently by primary and second-
ary links. Each link carries different Ethernet traffic. MHS does not
protect Ethernet traffic.
Note
Do not proceed unless this condition is fully met!
